valuate the student’s answer. A. Incorrect; the student should add 8 + 2 to calculate the x-coordinate and should add 5 + 9 to calculate the y-coordinate. B. Incorrect; the student added 4 to the y-coordinate instead of subtracting 4 from the y-coordinate. C. Incorrect; the student added 6 to the x-coordinate instead of subtracting 6 from the x-coordinate. OF. The student’s answer is correct.

Answer:

(x,y)\rightarrow (x-6,y+4)

Step-by-step explanation:

The rule of translation is defined as

P(x,y)\rightarrow P'(x+a,y+b)

where, a is horizontal shift and b is vertical shift.

The given point is J(8,5). After a translation the image of point J is J'(2,9).

J(8,5)\rightarrow J'(8+a,5+b)

The image of point J is J'(2,9).

J'(8+a,5+b)=J'(2,9)

On comparing both sides we get

8+a=2

a=2-8

a=-6

The value of a is -6.

5+b=9

b=9-5

b=4

The value of b is 4.

The rule of translation is

(x,y)\rightarrow (x-6,y+4)

It means 6 should be subtracted from x-coordinate and 4 should be added to the y-coordinate.

= 3x·2x + 3x·7 - 5·2x - 5·7

= 6x² + 21x - 10x - 35

= 6x² + 11x - 35
